Thisinvention relates to window screens and more particularly to devices for holding the ed es of window screens tightly against a wintw frame. i

There is now in general u se av window screen which may be wound upon a roller when not in use in the same manner as a window shade.

However, such screens, on account of their mounting and construction, have their side edges free, and as a result flies, bugsand other insects, are able to pass freely around the edges of the screen, there being an a preciable space between the screen and t e window frame, and consequently are objectionable in that res ect.

It is an object of t is invention to provide a device for tightly clamping the side edges of a screen, of the type described, against a window frame so that there will be no openings available for the entrance of insects and other undesirable things which the screen is intended to exclude.

A further object is to provide a clamping device which will occupy an inappreciable space so that it will not materially alter the' ap earance andstructure of the window.

hese and other objects are attained by the novel construction, combination and arrangement of parts hereinafter described and shown inthe accompanying drawing,

' strip 16, the latter having constituting a material part of this disclosure, and in which: v

Figure 1 is asectional view of a window equipped withthe clam ing device.

Figure 2 is a sectiona view showing the vposition of the parts when'the clamping device is not in use.

Figure 3 is a view similar vto that yof Figure 2 and shows the position of the parts when the clamping device is in use.

Figure 4 is a perspective view showing details of the clamping device.

Referring to the drawings and particu' larly to the perspective view in Figure 4, the clamping device is shown to include a plate 5 having slots 6 and 7 through which pins 8 and 9 pass, the pins being ixed to the plate 10'which is provided with a flange 11.

Fixed to late 5 are vpins 12, and 13 which pass throng slots 14 and15 in the clamping one edge in conf tact with the flange 17 o plate 5. The-op'- posite edge of theclamping strip 16 is pro-..

vided with cam surfaces 18 and 19 enga ed 'respectively by pins 8 and 9, so that w ien the strip 16 is moved upwardly the pins 8 and 9 will cam strip 16 and flange 17 `towards the flange 11, the slots 6 and 7 being proportioned to allow for the lateral movement of plate 5.

The strip 16 is manipulated by means of a lever 20 pivoted at 21 to plate 10 and having a slot 22 through which passes pin 23, the latter being fixed to strip 16. The outer end of the lever parses through a slot 24 in the 4 frame by means of a hinge 34 and screws 35.

In operation when the sash and the screen have been moved to desired positions, the free arm of lever 20 is depressed to raise the clamping strip 16, and the pins` 8 and 9 coact with cams 18 and 19. to force stri 16 and flange `17 toward Bange-11 to tight y clamp the side edges of the screen between the flanges 11 and 17.

From the above descri tion it will be seen that there has been provided an effective device for tightly clamping the side edges of a screen of the type described to prevent the 4 entrance of insects .and .other undesirable things. The device may be readily applied to a standard window without material alterations, and it occupies an inappreciable space, thus not affecting the usual appearance of the window.

The foregoing disclosure is to be regarded asdescriptive and illustrative only,'and not as restrictive or` limitative of the invention, of which obviousl an embodiment may be constructed inclu ing many modiications without departing from the general scope lherein indicated and denoted in the appended claims.

Having thus described my invention', what I claim .as new and desire to secureibyv Letters Patent, is:+ Y l v 1. A device for clamping the side edges of a window screen, comprising a stationary plate having a flange, a movable plate having a flange, pins on the stationary plate passing through slots in the movable plate, a

sur ces engaged by the pins, one edge of ysaid strip engaging the fiange on the movable plate, and means for moving the cam surfaces upward against the 'pins to cause lateral movement of the flange on the movable plate towards the flange on the stationary ate. p 2. In a device for clamping the side edges of a window screen, a movable plate having a flange, a longitudinally movable cam strip longitudinally movable strip having cam .having an edge engaging said Harige,- pins strip to move the flange laterally when the `strip is moved longitudinally.

3. In a screen clamping device, a movable plate a strip constant y engaging said plate vand longitudinally movable, inclined surfaces on one edge of the strip, and stationary lpins engaging said inclined surfaces to cause lateral movement of the strip and plate when the strip is moved longitudinally.

This specification signed this 14th day of June, 1928.
